I run a 445S with BSDI and the beta driver from them, and it is a SMOKING fast board. Really nice, it works, and I haven't seen ANY problems with it whatsoever. Other than crappy cables (which will screw you immediately as the board is a SCSI-II FAST implementation) and disks which died on their own (unrelated to the adapter). Highly recommended. I love mine, and will buy more. My primary news server here runs one.
